I am a Class 7 student and mobile enthusiast based in Nawada region of Bihar, India. I specialize in building high-performance native tools, Android applications, and custom terminal automation. All my development happens on mobile devices using Termux, proving that powerful software doesn't require expensive desktop setups.
System-Level Automation: Experienced with using Shizuku via CLI rish scripts to safely manage Android permissions and bridge the gap between Termux and native Android APIs.
An ultra-optimized, native C++ Android Build System designed specifically for the Termux environment to build Android APKs.
-
Key Achievement: Reached highly optimized incremental build speeds (down to ~5.79-10 seconds) by refining build trees and utilizing lightweight C/C++ architectures.

-
Features: Multi-subject formula database, automated custom test generator, interactive math quiz mode, multi-profile support, digital writing board, and a built-in note-taker and calculator.
-
Tech used: Java, Android SDK
-
Advanced Mathematics: Passionate about Number Theory, Geometry proofs, and Mathematical Induction.
-
Low-Level Android Mechanics: Tweaking, optimizing, and building lightweight binaries that bypass traditional mobile IDE resource overhead.
- Terminal: Termux with custom shell configuration including optimized aliases, functions, and build system integration
- Editors:
nanoand Code Studio (Android app) for writing efficient code on the go - Build Integration: Direct integration with Android SDK/NDK and custom build tools within Termux environment
"Constraints drive innovation. Building native tools on a phone proves you don't need a heavy desktop setup to write great software."
I'm open to collaboration, feedback, and discussing ideas about mobile development, low-level Android mechanics, or mathematics. Feel free to reach out!
